Nucleotide and amino acid sequence comparisons have shown that the reported spike gene from Indian isolates have 71.8%–99% and 71.4%–96.9% genetic similarity with the sequenced H120 strain. Genotyping of IBV strains can also be done by genetic characterization of the spike glycoprotein gene by reverse transcription polymerase chain reaction (RT-PCR), restriction fragment length polymorphism, and nucleotide sequencing, which for the most part correlates with the viral serotype [10, 11] . The deduced amino acid sequences of the spike glycoprotein from the Indian IBV vaccine strain and previously reported Indian isolates exhibited 71.4%-96.9% homology. In this study, we carried out propagation, amplification, sequencing, and bioinformatic analysis of the complete spike gene from the Indian vaccine strain, routinely used for vaccination of poultry birds. ./cache/cord-285052-aql0vrzv.txt ./txt/cord-285052-aql0vrzv.txt
